Abstract

In order to control the treatment of laser-induced interstitial thermotherapy, a new local control technique is put forward, which use a functional near infrared spectroscopy (fNIRS) system. The temperature of biological tissue is regarded as the most important indicator for treatment of LITT. So, based on the experiments of LITT being performed on a liver cancer, the temperature and reducing scattering coefficient have been obtained in real time, respectively, with probe-type thermometer and fNIRS system. The results of the two factors have the same trend with different power of laser. It is confirmed that the fNIRS can be a useful local control technology for LITT.
